Title: Document scanning and mark sensing apparatus
IPC: G06K7/10
Filed: 1966-11-22
Abstract: 1,145,307. Sensing records. INTERNATIONAL BUSINESS MACHINES CORP. 22 Nov., 1966 [7 Dec., 1965], No. 52213/66. Heading G4M. As a document is scanned by a beam, position signals representing the instantaneous positions of the beam are compared with reference signals from a counter controlled by the comparator, each reference signal corresponding to a different index position; and the state of the counter is gated out when a mark on the document is sensed. When card 1 arrives at the sensing position, switch 3 sets latch 25 to reset counter T1-T8, start a horizontal scan by C.R.T. 13 along the bottom edge of the card and set generator 29 to a predetermined level. When the first column mark 9 is reached, discriminator 31, controlled by the output from generator 29 provides an output pulse to reset latch 25, thereby stopping the horizontal scan, freeing counter T1-T8, and starting a linear upward vertical scan by means of AND gate 35, source 37 and capacitor C1. Since latch 25 is reset, generator 29 is set to a level corresponding to the darkest mark sensed during the linear vertical scan. When the scan reaches the top of the column, the voltage across C1 becomes equal to the normal output from amplifier 39 and discriminator 41 produces a first output pulse to enter a count of 1 in T1 and set TB via inverter 43 so that source 37 is turned off and source 45 is turned on. Thus the vertical scan is reversed, and each time, corresponding to the row positions on card 1, the output of amplifier 39 representing the count stored in T1-T8 is equalled by the decreasing voltage across C1, discriminator 41 produces another pulse to advance T1-T8. When a mark 7 is detected by discriminator 31 during the downward scan, the output at RO is used to gate out the decoded count stored in T1-T8 at that time. When the bottom margin of card 1 is again reached by the scan, T1-T8 reaches a count of 13 and AND gate 51 sets latch 25 to commence a horizontal scan search for the next mark 9.

Title: Signal selecting systems
IPC: G10H1/22
Filed: 1971-11-12
Abstract: 1369656 Electrophoric musical instruments MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 12 Nov 1971 [29 Nov 1970] 52600/71 Heading G5J A signal selecting system for a keyboard type electronic instrument comprises a plurality of tone signal sources 1-4, a plurality of gate means for controlling the feeding of said sources to amplifier 104, the gates being controlled by a plurality of memory means 21-24 associated with a plurality of switches 11-14. Each memory responds to the operation of a corresponding switch to assume a first or second condition in which it respectively opens and closes the associated gate 31-34. The tone signal soruces 1-4 are arranged in frequencies corresponding to a rising musical scale, and if, on closing switch 12 to a gate (32, say), reset means 42 is provided such that, if any memory corresponding to a frequency higher than 22, is holding its gate open, that memory will receive a reset pulse from reset means 42 via' diodes 53 ..., thereby returning said memory to first condition and closing the corresponding gate. This ensures that on simultaneous closing of more than one switch 11-14, only the tone source of lowest frequency will be fed to the amplifier 104. Diodes 51, 52 ... 53 prevent the reset signal reaching memories operating on signals of lower frequency. Further, the common reset means 101 detects a condition where two or more memory means are set in the second condition, by comparing the output D.C. potentials with a reference potential and resets any memory previously set. Memory means 21-24 may comprise a flip-flop circuit (not shown) or a cascade transistor switch circuit (not shown). Reset means 41-43 may comprise an electrical conductor, an isolating resistor or diode. Each gate means 31-34 comprises two resistors in series between generator 1-4 and amplifier 104. Actuation of each gate is controlled by the impedance of the memory output preserved at the junction of the resistors.

Abstract: 1,149,500. Indicating liquid levels. ROSEMOUNT ENG. CO. Ltd. 25 Oct., 1967 [25 Nov., 1966], No. 52892/66. Addition to 1,110,175. Heading G4H. A liquid level indicator comprises a plurality of capacitors located at different levels and connected to one pole of an alternating current source, and a plurality of subtraction circuits connected to the capacitors each arranged to give a zero output if the input currents are equal, and a non-zero output if the input currents are different, the connections to the subtraction circuits being such that for each discrete level of liquid the subtraction circuits provide a unique combination of non-zero signals, and a change of level from one level to the next changes the outputs of only one of the subtraction units. In the form shown the capacitors are formed between a central core 10a and a series of ring members 21-28. The rings are connected in groups to subtractors 37, 38, 39. Rings 22 and 26 are connected to diodes 41, 42, and rings 24 and 28 are connected to diodes 43, 44. Positive half-cycles pass through diode 43, and negative half-cycles through diode 42 to earth. Positive half-cycles pass through diode 41 and negative half-cycles through diode 44. The resulting signal is smoothed by RC circuit 45, 46. If the currents are balanced there is no output at 51. If not a signal appears at 51. The signals will be balanced if the liquid does not reach any of the rings 22, 24, 26 or 28. If the liquid reaches ring 22 the current passing through the capacitor is less and the subtractor 37 gives an output. When the liquid reaches ring 24, one ring of each pair is in the liquid and the currents again balance, so there is no output. When the ring 26 is immersed, a signal is produced, and when ring 28 is immersed there is again no signal. The other two subtractors are connected to other rings so that the output combination represents the liquid level in Gray code. In another arrangement the central core is earthed and the live pole of the source is connected to the other side of the subtractor circuits.

Abstract: 1,270,369. Gramophone. COLUMBIA BROADCASTING SYSTEM Inc. 11 Nov., 1970 [21 Nov., 1969], No. 53709/70. Heading G5R. In a record reproducer in which a pick-up support carriage 31 is mounted for radial movement relative to record 24 and has a pick-up 26 mounted thereon for movement relative to the carriage in the direction of carriage movement, the carriage is driven at a faster speed than that of the pick-up which is driven by the record groove and carriage drive decoupling means are brought into operation when the pick-up moves beyond a predetermined position relative to the carriage. The carriage is mounted on guides 34, 36 and driven by a half nut 62 which engages on eccentrically mounted lead screw 42 driven by friction wheel 44 engaging the record surface. The half nut 62 is mounted on an arm 64 which is spring urged about its pivot 66 towards the lead screw 42 and formed with a cut-out portion 72 and push button 74. Due to the eccentricity of the lead screw mounting, the nut 62 and arm 64 are reciprocated towards and away from the lead screw axis of rotation. The pick-up 26 is mounted on an arm 76 with oppositely directed lateral pivots 78, 80 by which the arm is mounted for pivoting and lateral movement in pillars 86, 88. In operation, due to the difference in pick up and carriage speeds the pick up moves towards pillar 86 moving, via an eye at the end of pivot 78, a spring wire member 90 until its tip enters the cut-out portion 72 of arm 64 as this moves downwardly following the eccentricity of the lead screw thereby disengaging the half nut until the pick-up resumes its initial position relative to the carriage and tangential to the record groove. As the pick-up enters the run-out groove, spring wire 124 is moved by the pick-up into the path of an oscillating lever 126. This then actuates a releasing member 112 which moves a detent portion of a spring 103 from the upper surface of the carriage and a further portion of the spring now engages an extension 100 of the pick-up arm to pivot the pick-up stylus out of engagement with the record. The assembly can be raised by upward pressure on knurled band 60 and swing about pillar 46 to a rest position. The radial position of the assembly is defined by a key 52 on pillar 46 which engages a keyway 54 in the cylindrical member 50 which is fast with the remainder of the assembly. On return of the assembly to the play position, the spring 103 is returned to its initial position to allow the pick-up stylus to engage the record by operation of push button 74.
